In the summer of 327, Callisthenes voiced protests against the introduction of proskynesis (an aspect of the Persian court ritual) among the Macedonians, and lost Alexander's favor ( more.). When Alexander was in Egypt, he sent his historian to Nubia, where he discovered the cause of the Nile flood and in Babylon, Callisthenes supervised the translation of the Astronomical diaries, which were used by Callipus of Cyzicus to reform the Greek calendars. During the campaign, Callisthenes' main duty was to write the Deeds of Alexander, but he was also sent on scientific missions. The two men may have met as members of the circle around the Macedonian philosopher Aristotle of Stagira, who was an uncle of the historian and the teacher of the future king.


In Alexander's company was a professional historian named Callisthenes of Olynthus (c.370-327), who had already published a Greek history of the years 387-356. Overview Official propaganda: Callisthenes Aristotle
